Management of Malignant Chylothorax with Subcutaneous Octreotide Treatment.

There are currently limited published case reports and clinical studies looking at octreotide as a potential therapeutic agent for treating surgery- and malignancy-related chylothorax in adult patients. Few case reports have shown that low-dose subcutaneous octreotide can be used to treat malignant chylothorax. We report the case of a 57-year-old high-grade follicular lymphoma patient with malignant chylothorax which responded rapidly and was successfully treated with octreotide. Significant improvements were noted in her dyspnea, abdominal distention and pain, and chylous output. This case also highlights the importance of understanding the pharmacotherapeutic effects of octreotide when managing malignant chylothorax as it may help to benefit patients by improving symptoms, quality of life, and length of hospital stay. Further prospective studies are warranted to further evaluate the role of octreotide in the management of malignant chylothorax.

Actual body weight dosing of temozolomide and overall survival in patients with glioblastoma.

BACKGROUND: Adult glioblastoma patients receiving standard radiation therapy and concurrent temozolomide chemotherapy have a median survival of 14.6 months. Based on the pivotal trial data by Stupp et al., temozolomide doses were calculated based on body surface area. However, no details regarding the weight used to calculate body surface area was included in the study. As a result, temozolomide doses have been variable across the province. METHODS: This retrospective chart review was conducted to determine the correlation between dose of first line temozolomide with overall survival. Patients between January 1st, 2009 and December 31st, 2014 who were newly diagnosed, pathology confirmed glioblastoma treated first line with temozolomide within Alberta Health Services were included in the study. Temozolomide doses above and below determined cut points were compared through the Kaplan-Meier method, then assessed using the log-rank test. RESULTS: A cut point of 97.8% of actual body weight calculated body surface area dosing was determined for concurrent phase temozolomide. At doses above this cut point, there was a statistically significant (p = 0.0158) increase of 0.3 years in median overall survival. As for toxicity concerns, there was a statistically significant increase in the proportion of temozolomide dose reductions due to toxicity in patients dosed above the cut point. CONCLUSION: Temozolomide doses at full actual body weight calculated body surface area dosing during the concurrent phase is required to achieve a similar median OS as seen in the pivotal trial by Stupp et al.
